A horror movie portrays victims of biological warfare with uncontrolled bleeding from the eyes, mouth, nose, ears, and anus. What actual virus causes these symptoms?

a. Ebola virus
b. Bunyavirus
c. Hantavirus
d. Human immunodeficiency virus

검증된 단계별 안내

Understand the symptoms described: uncontrolled bleeding from multiple orifices such as eyes, mouth, nose, ears, and anus. This suggests a hemorrhagic fever caused by a virus that affects blood vessels and causes bleeding.

Recall that hemorrhagic fevers are caused by several viruses, including Ebola virus, Bunyavirus, and Hantavirus, but their clinical presentations differ.

Identify that Ebola virus is well-known for causing severe hemorrhagic fever with widespread bleeding and high fatality, often involving bleeding from multiple body sites.

Consider that Bunyavirus and Hantavirus can cause hemorrhagic symptoms but typically have more specific clinical syndromes (e.g., Hantavirus causes pulmonary syndrome, Bunyavirus causes less severe hemorrhagic fever).

Recognize that Human immunodeficiency virus (HIV) does not cause acute hemorrhagic fever or uncontrolled bleeding, so it can be excluded from the options.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Hemorrhagic Fever Viruses

Hemorrhagic fever viruses cause severe illnesses characterized by fever and bleeding disorders. These viruses damage blood vessels and affect the body's ability to clot, leading to internal and external bleeding. Examples include Ebola and Bunyaviruses, which are known for causing outbreaks with high fatality rates.

Ebola Virus Characteristics

Ebola virus is a filovirus that causes Ebola virus disease, marked by sudden fever, muscle pain, and severe bleeding from multiple orifices. It spreads through bodily fluids and has a high mortality rate. The virus disrupts blood clotting and damages blood vessels, leading to the hemorrhagic symptoms described.

Differentiation of Viruses Based on Symptoms

Different viruses cause distinct clinical symptoms. While Ebola causes hemorrhagic fever with bleeding, Hantavirus primarily causes respiratory issues, HIV leads to immune suppression without hemorrhaging, and Bunyaviruses vary but often cause milder symptoms. Recognizing symptom patterns helps identify the causative virus.
